Answer:
24. 40 minutes approximately
25. 8 days
Step-by-step explanation:
24. 40 minutes
Anna: 1 hour
Peter: 3 hours
Maria: 6 hours
A way to solve this kind of question is to think about how much they can perform given the same amount of time.
Anna: 1 hour x 6: 6 hours (In 6 hours Anna can clean 6 houses)
Peter: 3 hours x 2 6 hours (In 6 hours Peter can clean 2 houses)
Maria: 6 hours x 1: 6 hours (In 6 hours Peter can clean 1 house)
Working together they can clean the house 9 times faster.
It is 0.66 hours, or approximately 40 minutes
25. 8 days

Step-by-step explanation:
Xavier and Bobby each receive a salary check every week. They combine their checks in one account. Their account has $100 after 2 weeks and $300 after 6 weeks.
In a graph showing the relationship of amount in their account versus time, time should be plotted on the horizontal X - axis.
To find the width, divide the area by the length:
27 / 6 = 4.5
The width is 4.5 inches.
